I installed my new Doorbell pro today after installing a new 16v transformer. All was good, power all around. Doorbell was working perfect and within 2 hours it was dead. There is no power going to the doorbell or doorbell chime. Could something have gotten fried through the new transformer?
Hi did you install 16v30Va. I had a 16V10va. I purchased the 16V30va and it has continuous power.
